“…Zeng, Lei, and Chen (in [30]) and He, Hu, and Fang (in [16]) have investigated a dynamical system with asymptotic vanishing damping attached to (1.1), and have shown a convergence rate of order O 1/t 2 for the primal-dual gap, while Attouch, Chbani, Fadili and Riahi have considered in [2] a more general dynamical system with time rescaling. More recently, for a primal-dual dynamical system formulated in the spirit of [2,16,30], Boţ and Nguyen have obtained in [8] fast convergence rates for the primal-dual gap, the feasibility measure and the objective function value along the generated trajectory, and, additionally, have proved asymptotic convergence guarantees for the primal-dual trajectory to a primal-dual optimal solution.…”
